The simplest optimal controls are preplanned (programmed) ones. The problem of constructing optimal preplanned controls has been extensively worked out in literature (see, e. g. , the Pontrjagin maximum principle giving necessary conditions of preplanned control optimality). However, the concept of op timality itself has a restrictive character: it is limited by what one means under optimality in each separate case. The internal contradictoriness of the preplanned control optimality ("the better is the enemy of the good") yields that the practical significance of optimal preplanned controls proves to be not great: such controls are usually sensitive to unregistered disturbances (includ ing the round-off errors which are inevitable when computer devices are used for forming controls), as there is the effect of disturbance accumulation in the control process which makes controls to be of little use on large time inter vals. This gap is mainly provoked by oversimplified settings of optimization problems. The outstanding result of control theory established in the end of the first half of our century is that control | | 出版日期 | Book 1996 | | 关键词 | Operator theory; control; control system; design; material; operator; optimization; systems theory | | 版次 | 1 | | doi | https://doi.org/10.1007/978-94-009-0127-8 | | isbn_softcover | 978-94-010-6544-3 | | isbn_ebook | 978-94-009-0127-8 | | copyright | Springer Science+Business Media Dordrecht 1996 |
